OpenIntelligence Full-Repository Line-by-Line Architecture & Line-Level Audit

Evidence Threads Feasibility & Security Verification

This document details the read-only, full-line repository audit and verification pass performed on the OpenIntelligence codebase. The primary objective is to mathematically prove line-level coverage across all first-party files, verify the current storage and routing architectures, and establish the safest implementation design for local-only Evidence Threads in Version 27 (supporting iOS 26/27, macOS 26/27).

2. Coverage Proof

Line-level coverage has been mechanically audited via custom parser utilities and Git tracking records. The complete file inventory and exclusions are cataloged in detail across the following artifacts:

Audit Commands & Scripts Used

The mechanical audits were executed using the commands and scripts documented in audit_commands_used.md. The main discoveries were run using:

  • git ls-files to discover tracked files.
  • git status --porcelain to identify untracked files.
  • generate_audit_artifacts.py to calculate line counts, verify line ranges, generate SHA-256 hashes, and catalog Swift symbol categories.

Architectural Stages & Specifications

  1. App Launch & Lifecycle: Governed by OpenIntelligenceApp.swift and ContentView.swift. Restores runtime states, configures directory paths via KnowledgeContainer.swift, and starts local monitors.
  2. Onboarding: Handled by OnboardingStateStore.swift. Checklist flags and query onboarding states are written to UserDefaults.
  3. Library / Container Creation: Scoped in ContainerService.swift. Groups documents into distinct KnowledgeContainer collections. Schema configurations are written atomically to containers.json.
  4. Document Import: Handled by DocumentPicker.swift and RAGService.swift. Source documents are copied to baseDir()/ImportedDocuments/ using unique index suffixes to avoid naming collisions.
  5. Ingestion Queue: Managed sequentially via RAGService.persistIngestionQueueState() and BackgroundTaskService.swift using ingestion_queue.json as a crash-recovery ledger.
  6. OCR / Extraction: Managed in DocumentProcessor.swift and LayoutAwareExtractor.swift. Parses text layers, falling back to Apple’s Vision OCR framework for images/scans.
  7. Semantic Chunking: Done via SemanticChunker.swift using sentence segmentation to build 280-400 word chunks.
  8. Embedding: Implemented in EmbeddingService.swift. Generates 384-dimensional floating-point vectors on-device using a CoreML Sentence Embedding model.
  9. Vector Storage: Managed via BNNSVectorDatabase.swift. Indexes are stored in vector_database_<containerId>.json plus associated binary vectors (_vectors.bin).
  10. SQLite / FTS5 Storage: Governed by SQLiteFullTextService.swift. Creates local-only virtual tables to support keyword lookups.
  11. Retrieval: Handled in HybridSearchService.swift. Cosine similarity vector search and FTS5 keyword queries run concurrently.
  12. Reranking: Fuses scores via Reciprocal Rank Fusion (RRF) in HybridSearchService.swift to merge lexical and vector outputs.
  13. Context Packing: Packs context in FoundationModelTokenBudget.swift up to the target token budget limit.
  14. Model Routing Policy: Evaluated in FoundationModelRoutePolicy.swift to choose the execution path.
  15. Local Apple Foundation Models: Generates completions on-device using the 3B Core model (SystemLanguageModel.default).
  16. Private Cloud Compute (PCC): Routes complex reasoning or large-context queries to secure PCC enclaves using PrivateCloudComputeLanguageModel.
  17. Verification Gates: Implements post-generation anti-hallucination checks in VerificationGateService.swift (evaluating Negation and Word-Overlap constraints across gates A-I).
  18. Citations: Maps claims to source document chunk snippets using SourceChipsView.swift.
  19. Chat UI: Renders SwiftUI message bubbles via ChatScreen.swift and MessageListV2.swift.
  20. Chat Persistence: Writes history records atomically to chat_history_<containerId>.json.
  21. Trace & Export Tools: Serializes prompt chains, RAG metrics, and execution times into Markdown traces via PipelineTraceExporter.swift.
  22. App Intents: Integrates with Siri via RAGAppIntents.swift.
  23. Background Tasks: Coordinates indexing, document sync, and cleanup loops via BackgroundTaskService.swift.
  24. iCloud Sync: Synchronizes metadata and document packages via WorkspaceSyncService.swift.
  25. Billing / Entitlements: Restricts libraries and document quotas via EntitlementStore.swift using StoreKit 2 APIs.
  26. Diagnostics / Telemetry: Emits runtime system logs via TelemetryCenter.swift and DeveloperDiagnosticsHubView.swift.
  27. Settings: Controls PCC preferences, active model overrides, and RAG tuning parameters via SettingsStore.swift.

4. Chat Persistence Truth

The adversarial audit of ChatMessage.swift and RAGService.swift resolved the following persistence parameters:

  • Is ChatV2 Persisted: Yes. ChatV2 is fully persistent.
  • Is the In-Memory Comment Stale: Yes. The comment at ChatMessage.swift line 37 claiming V2 is “in-memory only” is stale and contradicts the active saving code in RAGService.swift.
  • Writing File: RAGService.swift writes history to disk in saveChatHistory(_:for:) using WorkspaceSyncService.coordinatedWriteData.
  • Reading File: RAGService.swift reads history in preloadChatHistory(for:) (line 537) using WorkspaceSyncService.coordinatedReadData.
  • Is sanitizedForPersistence() Called: Yes. It is mapped over the message array in RAGService.persistChatHistory (line 569) prior to writing.
  • Container Switch Behavior: Switching containers triggers RAGService.persistChatHistory for the active container, swaps the active ID, and calls preloadChatHistory for the target container.
  • App Relaunch Behavior: Restores the last active ID from UserDefaults key "activeContainerId", preloads history from the corresponding JSON, and populates @State private var messages in ChatScreen.swift.
  • Retrieved Chunks Persisted: Yes, but pruned. The sanitization routine truncates the list to a maximum of 12 chunks, cuts each content snippet to 600 characters, and removes the heavy parentContent field to prevent disk bloat.
  • PipelineTrace Persisted: No. pipelineTrace and thinkingEvents are omitted from CodingKeys in ChatMessage.swift (line 85) and are never written to disk.
  • Citations Restorable: Yes. Because the truncated chunks and structured response metadata are preserved in the JSON, citations map correctly after relaunch.
  • User UGC Compliance Fields Persisted: Yes. User safety flags (isHidden, userReportedAt, userReportReason, userReportNotes) are included in CodingKeys and persisted to support App Review compliance.
  • Maximum Message Cap: Hardcapped in RAGService.swift (line 557) to 200 messages per container. Older messages are trimmed.
  • Breakage Risk of Monolithic Reuse: If Evidence Threads are stored directly in the existing chat_history_<containerId>.json (Design A), the global 200-message cap will prune older threads automatically when the total message count across all threads in a container exceeds 200.

5. Storage Map

The following map details the exact parameters for all ten storage substrates:

  • JSON:
    • Read Function: JSONDecoder().decode() via coordinatedReadData(from:) in WorkspaceSyncService.swift.
    • Write Function: JSONEncoder().encode() via coordinatedWriteData(_:to:) in WorkspaceSyncService.swift.
    • Atomicity: High. Writes use .atomic options and write to a .tmp file before renaming.
    • Migration Behavior: Class-based manual conversions (e.g., converting legacy document counters to DocumentPackEntry models in EntitlementStore.swift).
    • Sync Behavior: Uploaded to iCloud shared containers if sync mode is enabled.
    • Deletion Behavior: File deletion via coordinatedRemoveItem(at:).
    • Suitability for Evidence Threads: High. Conforms to the current file architecture.
  • SQLite / FTS5:
    • Read Function: SQL query execution in SQLiteFullTextService.swift.
    • Write Function: SQL insert/update transactions in SQLiteFullTextService.swift.
    • Atomicity: Transaction-protected.
    • Migration Behavior: Tables are dropped and fully rebuilt from original documents if schema version mismatch occurs.
    • Sync Behavior: Local-only; excluded from sync and rebuilt on-device.
    • Deletion Behavior: SQL delete queries or database file removal.
    • Suitability for Evidence Threads: Low. High transaction overhead.
  • Vector Store:
    • Read Function: BNNSVectorDatabase.load() parses JSON metadata and binary files.
    • Write Function: BNNSVectorDatabase.persist() writes vectors to binary arrays.
    • Atomicity: High. Temporary swap writes.
    • Migration Behavior: Rebuilt if index headers change.
    • Sync Behavior: Synced via iCloud.
    • Deletion Behavior: Direct file deletion.
    • Suitability for Evidence Threads: None (Mathematical formats only).
  • UserDefaults:
    • Read Function: UserDefaults.standard getters (e.g., string(forKey:)).
    • Write Function: UserDefaults.standard.set().
    • Atomicity: High. Managed by system sync.
    • Migration Behavior: Key names modified in settings.
    • Sync Behavior: Local-only.
    • Deletion Behavior: removeObject(forKey:).
    • Suitability for Evidence Threads: Low (Only suitable for scalar properties).
  • Keychain:
    • Read Function: Keychain lookups in StoreKitBillingService.
    • Write Function: Keychain writes in StoreKitBillingService.
    • Atomicity: Secure hardware-enforced transactions.
    • Migration Behavior: Managed by iOS Keychain services.
    • Sync Behavior: iCloud Keychain sync (if enabled globally).
    • Deletion Behavior: Item deletion.
    • Suitability for Evidence Threads: None.
  • iCloud Ubiquity Container:
    • Read/Write Functions: Coordinated via NSMetadataQuery and NSFileCoordinator sweeps.
    • Atomicity: File coordination locks.
    • Migration/Deletion Behavior: Handled dynamically by iCloud.
    • Suitability for Evidence Threads: None in Phase 1 (Must remain local-only).
  • CloudKit:
    • Status: Not Present in the codebase.
  • LocalCache:
    • Read/Write Functions: File manager utilities.
    • Atomicity: Depends on file operations (atomic JSON writing is recommended).
    • Sync Behavior: Strictly local-only. Parent folder matches localOnlyEntryNames.
    • Suitability for Evidence Threads: High. Guaranteed local-only.

6. Sync Boundary Map

The synchronization boundaries defined in WorkspaceSyncService.swift dictate the following behaviors:

  • Synced Today: containers.json, documents_metadata.json, ingestion_queue.json, chat_history_<containerId>.json, transcript_<containerId>.json, conversation_memory_<containerId>.json, and physical document packages under ImportedDocuments/.
  • Local-Only: The LocalCache/ directory (which holds FTS5/ databases and continued task states) is excluded from iCloud.
  • Accidental Sync Risk: If thread files are stored under AppSupportPaths.baseDir() (e.g. baseDir()/threads/ or baseDir()/evidence_thread_<id>.json), they will be accidentally synced because threads is not in localOnlyEntryNames. This will cause overwrites due to last-write-wins rules.
  • Conflict Strategy:
    • Metadata: Custom lists are merged by combining array keys.
    • Transcripts/History: Last-write-wins based on file modification timestamps.
  • Coordinated Utilities Safety: Bypassing WorkspaceSyncService.coordinatedWriteData is required because it posts a .localWorkspaceDidChange notification that triggers sync sweeps. A custom local-only atomic writer coordinatedWriteLocalOnlyData(_:to:) must be implemented.

7. Routing/PCC Map

Verification of FoundationModelRoutePolicy.swift and FoundationModelTokenBudget.swift reveals the following routing rules:

  • Local Routing Limit: Hardcoded to 4,096 tokens (route policy limit). Standard queries within this context length run locally via the 3B Core model (SystemLanguageModel.default).
  • Advanced Local Limit: On iOS 27+ / macOS 27+, Deep Think and Maximum mode queries can run on-device up to 8,192 tokens using the 20B Advanced model.
  • PCC Routing Limit: Supports up to 32,768 tokens using PrivateCloudComputeLanguageModel when context overflows or Deep Think/Maximum modes are triggered.
  • routing Discrepancy: The route policy limits standard local queries to 4,096 tokens to trigger PCC, even though FoundationModelTokenBudget claims on-device Apple FM context sizes support up to 8,192 tokens.
  • Consent Key Name: Stored under key "cloudConsent.applePCC" in UserDefaults.
  • Always Allow Persistence: Saves the state .allowed to settings, bypassing subsequent consent prompts.
  • Behavior when Consent Pending: Suspends execution using withCheckedContinuation until resolved in the UI sheet.
  • App Intent Background Deadlock Hazard: Siri background app intents (e.g., QueryDocumentsIntent) will deadlock indefinitely on the checked continuation if consent is .notDetermined because there is no UI view to present the consent sheet. This will cause background intents to time out.
  • Marketing Copy Guidelines:
    • Safe Claims: “Local-first processing”, “Secure scaling to Private Cloud Compute”, “Citation-backed grounds”.
    • Unsafe Claims: “100% on-device inference”, “Zero data leaves the device”.

8. Billing/Entitlement Map

Auditing EntitlementStore.swift and QuotaPolicy.swift establishes the following boundaries:

  • Product Identifiers:
    • pro_monthly ($5.99/month, subscription)
    • pro_annual ($49.99/year, subscription)
    • lifetime_cohort ($59.99, non-consumable)
    • doc_pack_addon ($2.99, consumable, adds 10 document slots)
  • Effective Tier Calculation: Derived from active StoreKit entitlements. Grandfathered users with historical paid transactions (historicalPaidPurchase, legacyDocumentPackOwner) bypass active StoreKit checks and default to effective Lifetime tier privileges.
  • Quota Limits:
    • Free: 1 library, 5 documents, 3 daily Maximum mode runs, no iCloud sync.
    • Pro: 10 libraries, 1,000 documents, unlimited Maximum mode, iCloud sync enabled.
    • Lifetime: 20 libraries, unlimited documents (.max), unlimited Maximum mode, iCloud sync enabled.
  • Sync Gate: iCloud shared workspaces are gated via EntitlementStore.currentEffectiveTier().isAtLeast(.pro).
  • Evidence Threads Constraints: Thread creation must read effectiveTier in EntitlementStore to apply limits (e.g., capping Free tier to 3 active threads per container) without modifying StoreKit validation.

9. App Intents Map

Verification of Siri integration in RAGAppIntents.swift reveals the following intents:

  1. QueryDocumentsIntent (Runs in background; reads document chunks; can trigger PCC routing).
  2. ListDocumentsIntent (Runs in background; reads document metadata).
  3. DocumentImportStatusIntent (Runs in background; reads ingestion queue status).
  4. AskDocumentIntent (Runs in background; reads specific document chunks).
  5. SummarizeDocumentIntent (Runs in background; reads and summarizes document content).
  6. CompareDocumentsIntent (Runs in background; reads and compares multiple documents).
  7. SearchLibraryIntent (Runs in background; queries container databases).
  8. IngestDocumentIntent (Runs in background; writes physical documents to disk).
  9. IngestURLIntent (Runs in background; writes crawled webpages to ingestion queue).

Shortcut Limits

  • Registered App Shortcuts: Exactly 9 shortcuts are registered.
  • System Limit: Apple limits applications to exactly 10 App Shortcuts in AppShortcutsProvider.
  • Safety Handoff: Since only 1 shortcut slot remains, Phase 1 Evidence Threads must NOT register any app shortcuts to prevent registration errors.

10. Evidence Threads Storage Design Challenge

Four candidate architectures have been evaluated for storing Evidence Threads:

Design A: Monolithic History Extension

  • Concept: Add threadId: UUID? to ChatMessage and save all threads in chat_history_<containerId>.json.
  • Data Loss Risk: Critical. The global 200-message container cap will silently delete older threads’ messages.
  • Sync Risk: High. Last-write-wins synchronization will overwrite threads concurrently updated on other devices.
  • UI Complexity: Medium (In-memory filtering required).
  • Overall Rating: Unsafe.
  • Concept: Store threads as individual thread_<threadId>.json files under LocalCache/EvidenceThreads/<containerId>/ managed by a central index.json.
  • Data Loss Risk: Negligible. Cap is applied per thread (e.g., 100 messages) preventing cross-thread deletions.
  • Sync Risk: Low. Isolates sync conflicts to the active thread file.
  • UI Complexity: Low (Direct file binding).
  • Overall Rating: Selected Design.

Design C: SQLite-backed Thread Store

  • Concept: Store transcripts in local SQLite database tables.
  • Data Loss Risk: Low.
  • Sync Risk: None (Rebuilt locally).
  • UI Complexity: High (Requires writing a SQL-to-Codable mapping layer).
  • Overall Rating: Unsuitable (Introduces transaction overhead and write contention).

Design D: SwiftData / CoreData Store

  • Concept: Store transcripts using Apple’s SwiftData framework.
  • Data Loss / Migration Risk: High. Schema migrations will fracture the established JSON persistence layers and complicate local file coordination.
  • Overall Rating: Unsuitable.
